Test conditions and notes10
- 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
- 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
- 3. Tolerance : includes set up tolerance, line regulation and load regulation.(In order to meet tolerance, it is recommended that CH1 load > 5% rated current.)
- 4. Line regulation is measured from low line to high line at rated load.
- 5. Load regulation is measured from 20% to 100% rated load, and other output at 60% rated load.
- 6. Each output can work within current range. But total output power can't exceed rated output power.
- 7. The power supply is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on a 360mm*360mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
- 8. Length of set up time is measured at cold first start. Turning ON/OFF the power supply very quickly may lead to increase of the set up time.
- 9. Testing harmonic current at 85%load.
- 10. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).

FAQ
Can I use the RID-125-1224 for 12V automation hardware in a control panel?
It can fit 12V automation hardware when the load remains within its 3.7A output current and 133.2W power rating. The enclosed construction and isolated dual output support panel-based power distribution for low-voltage control equipment.
Is the RID-125-1224 appropriate for 12V embedded controllers or industrial communication devices?
This model is aligned with 12V embedded or communication hardware because it provides a 12V output with 3.7A available current. It is better matched to devices that need a stable 12V supply than to equipment requiring 5V or 24V rails.
Can the RID-125-1224 support 12V monitoring, sensing, or interface equipment?
Yes, it can serve 12V monitoring or interface equipment in industrial and automation settings if the connected load is sized within 3.7A. The 133.2W platform gives more headroom than the smaller 50W, 65W, or 85W family members.
Is the RID-125-1224 suitable for outdoor cabinets or only indoor equipment spaces?
Its specified operating temperature range is -20°C to +70°C, which supports use in a wide range of equipment environments. The provided specs do not list an IP rating, so weather-exposed outdoor suitability cannot be confirmed from this data alone.
What are the main differences between the RID-125-1224 and the other RID models listed?
The sibling list includes RID-125-1205 at 125.4W, 12V/5V; RID-125-1248 at 138W, 12V/48V; RID-125-2405 at 125.4W, 24V/5V; RID-125-2448 at 144W, 24V/48V; RID-50A at 50W, 5V, 2A; RID-50B at 50W, 5V, 1.4A; RID-65A at 65W, 5V, 3A; RID-65B at 65W, 5V, 2A; RID-85A at 85W, 5V, 4A; and RID-85B at 85W, 5V, 2A. The RID-125-1224 stands out as a 133.2W, 12V/24V model with 3.7A output current per channel.
